The transition from an engulfed autonomous unicellular photosynthetic bacterium to a semiautonomous endosymbiont plastid was accompanied by the transfer of genetic material from the endosymbiont to the nuclear genome of the host, followed by the establishment of plastid‐to‐nucleus (retrograde) signaling. The retrograde coordinated activities of the two subcellular genomes ensure chloroplast biogenesis and function as the photosynthetic hub and sensing and signaling center that tailors growth‐regulating and adaptive processes. This review specifically focuses on the current knowledge of selected stress‐induced retrograde signals, genomes uncoupled 1 (GUN1), methylerythritol cyclodiphosphate (MEcPP), apocarotenoid and β‐cyclocitral, and 3′‐phosphoadenosine 5′‐phosphate (PAP), which evolved to establish the photoautotrophic lifestyle and are instrumental in the integration of light and hormonal signaling networks to ultimately fashion adaptive responses in an ever‐changing environment.

光和激素信号的塑性逆行调制:奥德赛

从吞噬的自主单细胞光合细菌向半自主内共生体质体的过渡伴随着遗传物质从内共生体到宿主核基因组的转移,随后建立了质体-核(逆行)信号传导。这两个亚细胞基因组的逆向协调活动确保了叶绿体的生物发生,并起着光合枢纽以及调节生长调节和适应性过程的传感和信号传导中心的作用。这篇综述特别关注了一些已知的应激诱导的逆行信号,不相关的基因组1(GUN1),甲基赤藓糖醇环二磷酸(MEcPP),类胡萝卜素和β-环柠檬醛以及3'-磷酸腺苷5'-磷酸(PAP)的当前知识,
